SUSTAINABILITY AND ENVIRONMENTAL MANAGEMENT CONFERENCE & EXHIBITION (SEM 2013) By: Datuk Ir. Abdul Kadir Mohd Din & Prof. Ir. Haniffa Hamid Indah Water Konsortium Sdn Bhd 23 October 2013 Kuala Lumpur PRESENTATION STRUCTURE Introduction Wastewater as an Alternative Water Source for Non Potable Use in Malaysia Wastewater Reuse Technology and Treatment Challenges and Barriers The Strategic Approach Way Forward & Summary (C) IWK/PED/1013 Objectives  To present an overview of use of treated wastewater effluent as an alternative water source; potential to reduce water footprint  To highlight the strategic approach for water reuse initiatives in Malaysia (C) IWK/PED/1013 Introduction • Malaysia Vision to become a fully developed country by the year 2020. • Rapid development has taken place in sectors like agriculture, industry, tourism, manufacturing and urbanisation. • All these development would not be possible without adequate water resources. • Despite the country’s wet humid equatorial climate regime, many parts of the country suffer from periodic water stress, primarily due to: • Imbalance water demand in varying locations and sectors. • Changes in weather pattern affect trends in precipitation & temperature. (C) IWK/PED/1013 Need Statement National Water Resources Study (2000-2050) – Water Stress States Penang, Melaka, Selangor , potentially N. Sembilan. Rapid Urbanization and Industrialization. During Dry season, water shortage & rationing To cope : Inter State supply; demand management; & efficient water use i.e. water recycling NEED TO REDUCE WATER ABUSE Potable water for Potable Uses Reclaimed Water for Non-Potable Use 30 d n a 25 s u o h 20 Potable t ( ) WATER d D 15 Irrigation n L a M DEMAND IN m Other Crops 10 e MALAYSIA IS D Livestock r 5 INCREASING e t a Fisheries W 0 2010 2020 2030 2040 2050 Year (C) IWK/PED/0713 Raw Water Resources in Malaysia – Current & Future Potentials Treated Direct Wastewater Extraction (4500 MLD) from River 12,620 MLD Rain Water Storage Dams Harvesting 2,274 MLD Ground Water Seawater 204 MLD (desalination) (C) IWK/PED/1013 Domestic Wastewater Dimensions and Network PERLIS KEDAH PULAU PINANG KELANTAN LABUAN PERAK TERENGGANU Many Regional STPs are located at ur ban areas i.e. the wate r demand areas; potential alternative water PAHANG SELANGOR resource WP KUALA LUMPUR NEGERI SEMBILAN “Indah” Water - 25% of National MELAKA an Alternative Potable Water JOHOR Water Resource Demand (C) IWK/PED/1013 The Present Situation TREATED EFFLUENT BOD < 5 mg/l BIOGAS BIOSOLIDS COD < 15 mg/l Methane – 65% N – 3%; P – 1%, K - <0.1% SS < 5 mg/l CV – 5000 kcal/m3 Organic Matter – 40-50% CV – 2000-3500 kCal/kg DS FLARE DISPOSE DISCHARGE ENERGY CONSUMPTION RM 0.10 to RM 0.50 per m3 of treated effluent HIGH CARBON FOOTPRINT GREEN HOUSE GAS EMISSION (C) IWK/PED/0713 Potential Resource Recovery in Sewage Treatment Biofertiliser Biosolids Biogas Biomethane n o i t aci de tn Kajian AAIBE sedang lp taeu dilaksanakan dengan UNITEN p elf A Composting rTfe r e s i l i tr Bioeffluent e F Kajian IWK-LGM: Kajian IWK-UTM: r o Aplikasi biopepejal sebagai Bioefluen untuk f Biogas Engine e Baja Tapak Semaian Getah Tumbuhan Landskap u Kajian IWK-UTM-JPP: la Aplikasi Membrane CMF v & RO pada Bioefluen t n e i r t u N Treated Electricity Effluent for Supply Kajian IWK-UPM: Kajian IWK-UPM: Biopepejal sebagai Biopepejal sbg baja Landscaping Baja utk Perhutanan Tanaman Getah Treated Effluent for Industries (C) IWK/PED/1013 Wastewater as an Alternative Water Source AGRICULTURE REUSE MUNICIPAL REUSE INDUSTRIAL REUSE • Crop Irrigation • 2nd Grade WATER • Private sector driven • Highest Demand in •Filling recreational parks • Well defined needs China, Mexico, India •Washing trucks and and requirements trains • Reliable supply • Cooling purpose •Public toilet flushing and • Low cost cleaning • Steam generation • Nutrient rich •Street washing and • Process water drain cleaning • Construction •Park Irrigation • Concrete mixing •Fire fighting • HIGH QUALITY • Tunneling WATER • Cleaning • Drinking Water supply (C) IWK/PED/1013
