4. Case Study Polluted Open Evaporation Pond Recycled industrial effluent Reclamation Demo Plant 1000m3/Day
Project objectives
Production 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)

5. AST Company Profile Years 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

6. AST Company Profile
Cooling Tower & Chemical Disposal Open Pond Intake Facility

7. Pre-Treatment Filtration
Ultrafiltration systems
Feed 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 ` , ~ Cod <450
Advantages
Low pressure
Low running cost (Power)
Backwash Rec. (High RR -98%)
Small Footprint

8. RO-Revers Osmosis Two Passes RO Systems
UF Product is treated by two Passes of RO membrane for eliminating the dissolved matter using low fouling membranes
TDS Product ~ ppm TDS
Advantages
High TDS resistance
Reject Rec.
High recovery ~ 86%

9. Brine Recycle Kit Vibrating mambrnes AST-SEP
RO 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
Low pressure
Treat non-degredables
Remove Gases & D.O
Small Footprint

10. Optional upgrading C-EDI Polishing
Ultra pure (high pressure boilers feed water) water production
By use of advanced Membranes technology -
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

11. Rejects treatment Solid Waste plant
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
