Industrial wastewater treatment, water reuse and waste solutions
Water in, effluent out, sludge and waste left over. We engineer all four as one system — recovering what has value before deciding what has to be disposed of.
The sector
Overview
Environmental engineering is Glorinda's largest and most specialised practice. It covers four connected problems that industrial and municipal operators rarely get to solve separately: the water going into a process, the effluent coming out of it, the sludge that treatment produces, and the solid and hazardous waste the site cannot send anywhere else.
We approach all four the same way. Characterise the stream properly. Choose the process against that data rather than against a catalogue. Recover whatever has value — water, salt, metals, nutrients, calorific content — and only then decide what genuinely has to be disposed of. That order matters commercially as well as environmentally: on most industrial sites the cost of disposal is now rising faster than the cost of treatment.
What sits inside this sector
Water and wastewater treatment. Industrial water treatment plants, industrial and municipal wastewater treatment plants, seawater desalination plants, and water reuse and recovery systems. Delivered as complete packages, or as the pre-treatment, main treatment, post-treatment or sludge stage inside a wider plant. Our process toolbox runs from dissolved air flotation and adsorption through membranes and biology to evaporation and crystallisation.
Waste management. Hazardous, industrial, solid, liquid, gaseous and mixed waste — characterisation, treatment process selection, incineration with flue gas treatment and bottom-ash handling, resource recovery and waste valorisation. Our incinerator packages are designed for hazardous zones (Zone 1 and Zone 2) and are compatible with gas groups IIA, IIB and IIC.
Sludge management. The line item that quietly dominates the operating budget of a treatment plant. Dewatering by screw press, centrifuge, filter press or belt filter press; mechanical and thermal drying; incineration with energy recovery; and thermal hydrolysis where the objective is more biogas and less residual volume.
Direct lithium extraction. An adjacent application of the same separation science — sorbents, simulated moving bed systems, calcium and boron removal, and dedicated lithium/sodium separation resin units — delivered with EPC services covering design, supply, installation and operator training.
How the work reaches you
Most environmental projects arrive in one of three shapes. A plant has a problem it cannot design around and needs someone to characterise it honestly. A new plant or expansion is defined and needs a technology partner who can carry a package. Or an EPC contractor and their client have already chosen the process and need a supplier who can deliver it and stand behind the performance. We work in all three, and the first conversation is deliberately technical in every case.
Civil construction is executed by local contractors. Glorinda supervises erection, integrates the process, and commissions and starts up the plant. That division keeps construction risk with the party who can price it properly and keeps process performance with us, where it belongs.
Value chain
Where we sit in the value chain
A treatment plant is a sequence, and money leaks at the joins. Pre-treatment that is undersized makes the main stage expensive to run. Post-treatment specified without knowing the upstream recovery target produces water that is either too good or not good enough. Sludge handling designed last becomes the single biggest operating cost on site.
We design the sequence as one system, and we are just as willing to be brought in for one stage of it — provided we can see the whole line.

Characterisation
Wastewater or feedwater analysis, load profiling and variability assessment. Nothing useful can be selected before this. Where a client has no reliable data, we define the sampling campaign that will produce it.
Pre-treatment
Physical, chemical and biological removal ahead of the main stage: dissolved air flotation, filtration, membrane separation, anaerobic biology, adsorption. Effective pre-treatment reduces cost in the main stage and improves overall process efficiency — on a ZLD line it can decide how many evaporators you have to buy.
Main treatment and recovery
Membrane recovery through conventional RO, closed circuit RO and high-efficiency RO; biological treatment including anaerobic membrane bioreactors; and where discharge must reach zero, evaporation and crystallisation.
Post-treatment
Ion exchange, mixed bed, electrodeionization and advanced oxidation to reach process, boiler feed, ultrapure or potable quality — drawing on Glorinda Resins' catalogue of more than 200 resin types.
Residue management
Sludge dewatering, drying and incineration; salt and solid output routed to compost, fertiliser, animal feed, backup fuel, saleable salt or, as a last resort, compliant disposal.
Operation
Commissioning, start-up, operator training, performance monitoring and after-sales technical support. We treat maintenance as an engineering activity, not parts replacement: the question is why a component wore, not just which one to fit.
Applications
Typical applications
Industrial water treatment
Process water, boiler feed water, cooling water and demineralised water production for plants where water quality is a production variable, not a utility.
Industrial wastewater treatment
High-COD, high-TDS, high-colour, solvent-laden and toxic streams that conventional biology cannot handle on its own.
Municipal wastewater
Sewage treatment plant design, upgrade and optimisation, including membrane bioreactor conversions where the site has no room to expand.
Seawater desalination
Reverse osmosis desalination plants with pretreatment matched to the intake, and brackish water systems for inland supply.
Water reuse and recovery
Closing loops on cooling blowdown, rinse water, white water and treated effluent so fresh intake and discharge volumes both fall.
Waste treatment and valorisation
Hazardous and industrial waste treatment, high-efficiency incineration with energy recovery, and material and resource recovery.
Problems
Common challenges
Every line below is a real operating problem raised by plants in this sector, matched to the capability that answers it.
Consent conditions move; plants do not. We assess whether the existing line can be upgraded — adsorption, advanced oxidation, membrane polishing — before anyone proposes a new plant. Where discharge has to reach zero, ZLD is the endpoint, but it is rarely the cheapest first move.
A permit that caps abstraction caps production. Recovery from existing streams is usually cheaper and faster to permit than a new source. Minimum liquid discharge recovers around 85% of a wastewater stream on membrane technology alone.
Aerobic treatment spends electricity to destroy organic load. AnaeroMBR converts the same load into biogas, with up to 98% COD removal, no aeration and up to 75% less sludge than an aerobic process.
Volume reduction is the only durable answer. Dewatering, then drying, then incineration — each stage removes moisture and haulage. Thermal hydrolysis before digestion improves digestibility, raises biogas yield and reduces residual volume.
Our adsorbent systems remove up to 90% of COD without electricity, take COD down to 50–70 ppm through a simple flow-through process, and address heavy metals (including up to 99.5% of lead), cyanide, pesticides, silica, ammoniacal nitrogen and colour — producing under 1% waste against around 30% for an RO system.
On-site hydrogen peroxide generation makes oxidant from water, air and electricity. No bulk chemical storage, no transport risk, no handling exposure — and it integrates directly into advanced oxidation, cooling water and odour control duties.

Water and wastewater is the deepest part of this sector and the part clients most often arrive at first. The dedicated section covers pre-treatment, main treatment and post-treatment in full, with a technology page behind every process route, and sets out how sludge management connects to bio-energy recovery.
That section is being expanded into its own dedicated site. Everything published here is the current, complete offering; the deeper technical library will live at the water subdomain as it goes online.

FAQ
Frequently asked questions
Which industries do you treat water for?
Oil and gas, refining and petrochemical, power generation, chemical, fertilizer, food and beverage, dairy, pharmaceutical and biotech, electronics and semiconductor, mining and steel, textile, pulp and paper, agriculture and agro-processing, and municipal utilities. Each has its own characteristic streams, and the water and wastewater section is organised around them.
Can you take responsibility for a complete treatment plant?
Yes. We deliver complete water and wastewater treatment packages on a turnkey basis as EP, EPC or EPCM, and we regularly act as owner's engineer for clients who are contracting the plant themselves. Civil works are executed by local contractors under our engineering supervision.
Do you work with EPC contractors as a package supplier?
Frequently. A large share of our environmental work is supplying a technology package — pre-treatment, ZLD, post-treatment or sludge — into an EPC scope, with performance guarantees on the package and FAT before shipment. We are used to vendor qualification processes and to being one name on a long bidder list.
How do you choose between MLD and ZLD?
By what the discharge consent and the water balance actually require. MLD recovers around 85% of the stream on membranes alone and costs materially less to build and run. ZLD takes recovery close to 100% but adds evaporation and crystallisation. If a site can legally discharge a small, concentrated brine volume, MLD is usually the better commercial answer; if it cannot, ZLD is the answer and pre-treatment design decides what it costs.
What happens to the solids at the end of a ZLD process?
Depending on the feed, the solid output can be converted to organic compost at 30% w/w moisture, incinerated at around 70% w/w concentration with a backup fuel such as wood waste or bagasse, used as organic fertiliser or animal feed as a dry non-hygroscopic powder at 98% concentration, or — where the effluent carries valuable salts — crystallised into a saleable or reusable salt. Disposal by complete drying or landfill is the last option, not the first.
