Biogas

As a major palm oil exporter of the world, Malaysia needs to have a trustworthy solution to the management of methane emission so that it reduces the negative impact to the environment.

Our passion and mission in promoting green technology has led us venture into BIOGAS Technology and we able to create robust and global partnership with ADI Systems Asia Pacific (Former members of Waste Solutions/ CPG Global, New Zealand).

Biogas is used to replace liquid fuel like petrol, diesel and boiler fuel or to produce electricity and heat.

ADI SYSTEMS’ CAPABILITIES & SPECIALIZATION

  1. ANAEROBIC TREATMENT
  2. Anaerobic treatment is a process in which microorganisms convert organic matter into biogas in the absence of oxygen. Anaerobic treatment is an energy-efficient process that is typically utilize to treat high-strength industrial wastewaters that are warm and contain high concentrations of biodegradable organic matter (measured as BOD, COD and/or TSS). An anaerobic system can be used for pretreatment prior to discharging to a municipal wastewater treatment plant or before polishing in an aerobic process.

    Anaerobic technologies offered by ADI Systems include:

    1. ADI-BVF®
    2. This patented low-rate anaerobic system combines features of the upflow anaerobic sludge blanket and anaerobic contact systems. It efficiently treats wastewater streams of moderate to very high organic strength and can accept high concentrations of suspended solids and some fat, oil, and grease, as well as digest waste activated sludge.

       

    3. ADI-CGR
    4. A robust low-rate anaerobic system used primarily for bioenergy production (in the form of biogas). This technology is ideal for waste-to-energy projects where the low cost and high-energy yield offer excellent returns. It is suitable for treating a variety of organic wastes.

       

    5. ADI-ECSB
    6. An ultrahigh-rate anaerobic treatment process which is highly compact. This technology is offered under license from HydroThane STP®.

       

    7. ADI-AnMBR
    8. A high-rate anaerobic process with membrane separation. It has a small footprint and produces the highest quality effluent. It is suited to high COD/TSS wastewaters with some FOG.

       

    9. ADI-CSTR
    10. A moderate-rate, continuously stirred, anaerobic process. It is suitable for a variety of waste streams, including those with a high solids content.

       

    11. ADI-Hybrid
    12. A proprietary high-rate system that combines two anaerobic processes. The upflow anaerobic sludge blanket at the bottom and upflow fixed-film at the top retains the process advantages of each.

       

  3. AEROBIC TREATMENT
  4. ADI Systems has aerobic treatment technologies that act as stand-alone treatment systems for treating the raw wastewater or provide aerobic polishing of anaerobically pretreated wastewater for further removal of BOD, TSS, nitrogen, and phosphorus. Aerobic treatment can also be used specifically for removal of nitrogen, and phosphorus - also known as BNR, or biological nutrient removal system.

    ADI Systems has extensive experience designing and building aerobic treatment systems worldwide for stand-alone treatment systems or to polish anaerobic effluent to meet a variety of discharge limits. Our ADI-MBR technology is capable of producing very high-quality effluent with very low effluent nitrogen and phosphorus concentrations, suitable for meeting strict discharge limits. ADI-MBR effluent also meets RO feed water quality for tertiary treatment.

    Aerobic technologies offered by ADI Systems include:

    1. ADI-SBR
    2. The sequencing batch reactor (SBR) is an advanced form of activated sludge technology whereby all biological process reactions, as well as settling/clarification take place in the same reactor vessel. The SBR removes organic material and suspended solids, like conventional activated sludge systems, plus it can also be used to biologically remove nutrients-nitrogen and phosphorus.

       

    3. ADI-MBR
    4. The membrane bioreactor (MBR) system is an activated sludge technology whereby a submerged physical membrane barrier is utilized to provide the liquid-solids separation instead of gravity clarification. This eliminates problems with sludge settling and separation and also provides a very high degree of treatment, meeting strict effluent limits. MBR technology is widely accepted as both a wastewater treatment and a water-reuse and recycling technology and provides a number of significant advantages to aerobic wastewater treatment.

       

  5. CONVENTIONAL ACTIVATED SLUDGE PROCESS
  6. Conventional activated sludge systems commonly include an aeration tank and secondary clarifier. Aerobic biomass reduces the BOD and ammonia concentrations in the aeration tank. Biomass then flows to the secondary clarifier, where it is separated into clarified water and thickened biomass by gravity sedimentation. The clarified treated water overflows at the top of the secondary clarifier, and the thickened biomass is recycled to the aeration tank or managed at sludge dewatering facilities.

  7. BIOGAS TREATMENT AND UTILIZATION
  8. ADI Systems has considerable experience offering complete biogas handling, treatment, and utilization systems for the recovery of renewable energy as part of its anaerobic treatment systems.

    The biogas generated as a by-product of the anaerobic digestion process consists of mainly methane and carbon dioxide. It is a valuable product for the replacement of conventional non-renewable energy sources like natural gas or other fossil fuels to generate electricity. It provides a significant amount of potential revenue for industrial end users.

    Biogas is commonly polluted with hydrogen sulfide (H2S), where concentrations can range from 100 ppm up to several %. H2S removal is required to reduce health risks and the corrosion of piping, gas engines, and boilers, as well as to reduce sulfur emissions to the atmosphere, ADI Systems offers H2S treatment of biogas using biological scrubber and chemical removal technologies. ADI Systems can provide biogas utilization packages in the following applications:

    • Internal Combustion Engines
    • Gen-sets
    • Micro turbines
    • Fuel Cells
    • Boiler and Steam Generating Systems
    • Sludge Dryers
