Refinery ZLD retrofit
High-TDS effluent taken to near-zero discharge with heat-integrated evaporation and crystallisation.
Environment · EN
From pre-treatment to ZLD, from sludge to energy, Glorinda engineers water, wastewater and waste systems that meet tightening discharge limits, recover water for reuse and cut the cost and footprint of every litre and every tonne.
Environment overview
Environmental services are one of Glorinda’s core activities. We provide industrial and municipal water and wastewater treatment, seawater desalination, sludge management and waste management — as engineering, procurement, integration and turnkey packages.
Our focus is maximising water recovery and minimising environmental impact by avoiding outdated methods and using advanced, efficient systems. We design each process around the real stream: its volume, its contaminants and the client’s discharge and reuse goals.
The economics usually turn on how far up the recovery curve it is worth going. Minimum Liquid Discharge recovers around 85% of a stream using conventional RO, closed-circuit RO and high-efficiency RO — a cost-effective alternative to thermal evaporation, and the right answer for most sites. Zero Liquid Discharge takes recovery close to 100% and leaves essentially nothing to discharge, but it costs more to run. We size that decision against your permit, your water cost and your expansion plans rather than defaulting to the most complete solution available.
Two capabilities sit underneath most of our work here. Our adsorbent systems remove up to 90% of COD through a simple flow-through process without electricity, take out heavy metals including up to 99.5% of lead, and address cyanide, pesticides, silica, ammoniacal nitrogen and colour — while producing under 1% waste against roughly 30% for RO, and regenerating on site for hundreds of cycles. And Glorinda Resins, our own subsidiary, supplies the ion exchange, mixed bed and EDI media that take recovered water to ultrapure quality for reuse in boilers, cooling and process.
Value chain
We design processes around individual requirements, broadly in these stages.
Physical, chemical and biological treatment — DAF, RO, UF, membrane and adsorbent steps that reduce load and cost downstream.
Biological and membrane treatment (incl. AnaeroMBR and MBR) to remove COD, BOD, solids and nutrients.
MLD for ~85% recovery, or ZLD for near-100% recovery where discharge is restricted or water is scarce.
Ion exchange, mixed bed, EDI and AOP to reach ultrapure quality for reuse in boilers, cooling and process.
Dewatering, drying, THP and incineration — turning residual sludge into biogas, compost, fuel or safe cake.
Available solutions
The full offering: pre-, main and post-treatment as turnkey packages.
Near-100% recovery for restricted or water-scarce sites.
Treat high-COD wastewater and turn organics into biogas.
Dewatering, drying and THP to cut volume and recover energy.
Hazardous-waste incineration, leachate and material recovery.
Ion exchange, mixed bed and EDI for ultrapure water.
Water solutions
Water and wastewater is deep enough to warrant its own space. Explore the full pre/main/post offering, sludge and the technology set — with links onward to our water subdomain.
A dedicated water subdomain hosts the deep content.
Case studies & projects
High-TDS effluent taken to near-zero discharge with heat-integrated evaporation and crystallisation.
MLD package recovering ~85% of process effluent for reuse in utilities.
THP and anaerobic digestion cutting sludge volume and producing biogas.
Yes. Glorinda engineers industrial water and wastewater, municipal sewage treatment and seawater desalination, as packages or turnkey projects.
It depends on the stream, but MLD typically recovers around 85% cost-effectively, and ZLD targets near-100% where discharge is restricted or water is scarce.
We design to your permit. The process is selected from the contaminant profile and the discharge or reuse target, not from a fixed template.
Yes. Sludge dewatering, drying, thermal hydrolysis (THP) and incineration are part of the offering, turning residual sludge into biogas, compost or fuel where possible.
