EnviroTex® process for batik effluent

EnviroTex® process biologically treats and decolourises batik effluents thus turning batik plants into ecofriendly industries. The process enables recovery of silicate and water for reuse, while not relying on chemicals for treatment, thus lowering treatment operational costs through minimum chemical usage (only for silicate recovery as well as pH correction) and zero hazardous waste. The process employs proprietary EMM® multimedia for adsorption and biofilm attachment, and conditions favouring biodegradation of dyes and other organics found in batik effluents.

R&D Project in Perhentian Island, Terengganu: Solar Still System for Treatment of Sewage (+

sanitary) Water• To investigate the use of a stepped solar still to improve

sewage management• Advantages:

The solar still system is the simplest technology and is an ideal solution to be used in rural and isolated areas since it uses solar energy (the ecofriendly energy sources) for heating water.

A decentralized wastewater treatment technology. Wastewater will be treated at source without the need to construct long and expensive pipeline networks and huge central wastewater treatment plants.

The high quality treated wastewater provides a prospect for water recycle and reuse. Solar distillation has been to provide fresh water in locations where water quality is poor, fresh water supply is inadequate, treatment options are not available and sunshine is abundant.

FUTURE PROGRAMMES: Artificial BioMacropore for Enhancing Soil Infiltration for Urban Catchment

• A heavy storm rainfall with either short or long duration

can cause flood inundation in urban catchment that exhibit high percentage of sealed surface.

• The sealed surface gives a large contribution on increasing runoff and reducing soil water infiltration.

• Therefore, some techniques are essentially required to overcome this problem.

• The presence of both natural and artificial soil macropores could increase saturated soil hydraulic conductivity by several orders of magnitudes.

• As a result, rainfall infiltrates rapidly into soil, conversely runoff and flood inundation will be reduced.

Page 57

FUTURE PROGRAMMES: Artificial BioMacropore for Enhancing Soil Infiltration for Urban Catchment

• This project involved evaluating an artificial

biomacropore as a media to enhance soil infiltrability in urban catchment as well as in HTCKL.

• Local community can participate in this project.

FUTURE PROGRAMMES: Rural River Rejuvenation (R3): Proposed Pilot R3 Project at Jenderam River, Sepang, Selangor [UNESCO-HELP Langat River]

• A means of bringing aquatic life back to rural rivers and cleaning up their waters so as to be fit for recreation.

• Main functional purpose would be to provide a water based recreational site to a rural community as well as to others.

• The rationale for the project is the lack of recreational opportunities for families to play together and for youngsters to spend their energies can lead to negative impacts on families and society. Although this is a recognised problem in Malaysia, which may contribute to delinquency, drug addiction and various other societal problems, solutions are seldom followed to the root, or implemented.

• Through R3, recreational sites for water based activities, as well as for fishing, picnicking, camping, etc, can be made available to surrounding villages.
