Case Study Polluted Open Evaporation Pond Recycled industrial effluent Reclamation Demo Plant 1000m3/Day

Project objectivesProduction of Alternative high quality industrial water From raw Polluted Pond chemical &heavy petrochemical industrial Plants effluent.

Target recovery is 92% RR Water to be used as cooling water, process water, irrigation and high pressure Boiler feed water (ultra-pure water)

AST Company ProfileYears of experience, Knowledge and development at:• Membrane Based solutions to treat sea water, brackish water and well water• Wastewater treatment and effluent recovery – For Oil & gas industry, Metal processing, mining, leachate • COD treatment Via AST patented Advance Sonic Oxidiation process.• Application of specialized formulations/chemicals for water treatment• Vibratory membrane systems VSEP for Ultra high Recovery of Waste water, chemicals and brine streams• Sea water Desalination and water recycle projects

AST Company ProfileCooling Tower & Chemical Disposal Open Pond Intake Facility

Ultrafiltration systemsFeed screened Blend water (several open pound high TDS high Cod source of water) is treated with SF +UF systems for eliminating the TSS and the turbidity of the Open Pound Feed water TDS `5000-6000, ~ Cod <450

Advantages• Low pressure• Low running cost (Power)• Backwash Rec. (High RR -98%)• Small Footprint

Pre-Treatment Filtration

Advantages• High TDS resistance• Reject Rec.• High recovery ~ 86%

Two Passes RO SystemsUF Product is treated by two Passes of RO membrane for eliminating the dissolved matter using low fouling membranes TDS Product ~ 150-200 ppm TDS

RO-Revers Osmosis

• Low pressure• Treat non-degredables• Remove Gases & D.O• Small Footprint

Brine Recycle Kit Vibrating mambrnes AST-SEPRO brine is recycled with High pressure & vibrating unit to reclaim Brine water from RO operation at 85-90% Recovery rate eliminating COD, Heavy metals , High Silica & Sulphate

Optional upgrading C-EDI Polishing

How?!CEDI is a technology that combine electromagnetic field with Resins and membranes. Polishing CEDI modules removes the traces of TDS from the RO product to produce ions free water

EDIUltra pure (high pressure boilers feed water) water productionBy use of advanced Membranes technology -

Rejects and brines back to evaporation pound Treatment

The reclamation plants produce (as a by product)solid waste from the membrane process with high TDS brines streams are send to disposal in conjunction of environmental regulations demands parameters
