process water discharge Applications

  • Zero Liquid Discharge wastewater solution

    Zero Liquid Discharge (ZLD) describes a process that completely eliminates liquid discharge from a system. The goal of any well-designed ZLD system is to minimize the volume of wastewater that requires treatment, process wastewater in an economically feasible manner, while also producing a clean stream suitable for reuse elsewhere in the facility. Interest in ZLD technology has grown in the industrial manufacturing sector over the past decade. Companies may begin to explore ZLD because of ever tightening...

  • Treatment of Process Water within Industry

    Water is used for a wide variety of purposes in industrial production. Water has to be treated, so that sufficient amounts are available in the quality required for production. Process water must generally be re-treated after it has been used, so that it can either be discharged according to regulations or returned to the water cycle.

  • Process design & engineering services for water treatment industry

    Waste water is any water that has been adversely affected in quality by anthropogenic influence. Municipal wastewater is usually conveyed in a combined sewer or sanitary sewer, and treated at a wastewater treatment plant or septic. Treated wastewater is discharged into receiving water via an effluent sewer.

  • Process monitoring and controlling for wastewater treatment industry

    Automation can save money, optimise a process and give warning of potential breeches of discharge consent. However, instrument selection is fundamentally important if a control system is to function efficiently. The measurement device must accurately and quickly respond to process variations and it must be reliable in operation if the control system is to function as intended. Designed properly, energy and chemical use can be significantly reduced, saving money and ultimately improving effluent quality.

    Water treatment solutions for utility water treatment

    It makes economic sense to reuse process water. Why would you discharge water just because you`ve used it once? If this water is treated properly, it can be reused with ease, cutting costs in no time.

    Monitoring of hydrocarbons in bilge water

    Various processes onboard ships, such as machinery wash-down, maintenance, and leakage, generate oily wastewater. This contaminated water flow collects in the bilge of the ship. Marine diesel, lubricating oils, grease, as well as other contaminants may be present in bilge water. The bilge water is discharged overboard, with oil and grease concentrations in the discharged water limited by national and international regulations.

    Water treatment solutions for the industrial water supply industry

    Water is widely used in industry, whether it is encountered as raw water, process water or waste water. Very often this water must be treated before entering the process to ensure its quality and properties will meet the specifications demanded by the industrial process. In addition, with recent discharge regulations and policies towards zero liquid discharge, there is a high demand for solutions for recycling and reuse of waste water produced. Lenntech provides sustainable and complete solutions for water and...

  • Biological wastewater processes for mining

    The mining industry has the potential to use large amounts of wastewater in its operations. Often times these waste streams contain contaminants that require treatment before the water can be re-used or discharged. Biowater has successfully installed highly efficient biofilm treatment processes including our complete mix fixed film (CMFF®) system to remove BOD/COD, and nitrogen from mining waste streams. Biowater’s technologies, such as our CFIC® process, can produce effluent water quality...

    Water Testing for Textile Manufacturing

    The textile manufacturing industry encompasses many and diverse processes that rely heavily on the use of water, energy, chemicals, and other resources. Wet spinning, sizing, desizing, scouring, bleaching, mercerization, dyeing and printing are just a few. Monitoring and controlling the pH, TDS/Conductivity/Salt Concentration, ORP (REDOX), and Temperature of the aqueous solutions used in these processes conserves costly resources, controls quality, and reduces the amount of pollution that must be treated...

  • COD Reduction

    Chemical Oxygen Demand (COD) is used as a measure of organic pollutants in water. In wastewater treatment, it indicates the efficacy of a treatment process and is expressed in milligrams per litre (mg/L) or parts per million (ppm). Removing certain fractions of COD in waste streams can be particularly challenging, especially to levels safe for discharge to the environment.

  • Water measurement systems & sensors for water quality monitoring

    Effective water quality monitoring is the key to environmental protection of watercourses and for reliable process control and wastewater treatment.  Discharge consents under EPR regulations dictate that water quality monitoring is undertaken to ensure that consented parameters are below the consented concentrations.  Traditionally this has been done using water quality sampling methods but increasingly automatic water quality measurement sensors linked to real-time telemetry is seen as the most...

  • Waste water respirometry solutions for toxicity reduction tests

    In industrial manufacturing companies, before a new process comes on-line, it is important to measure the toxicity of the effluent stream. This is especially the case for companies who treat their own waste. From the toxicity value (EC50) obtained, it may be a cost-effective solution to simply discharge the effluent to the treatment works at a slow and defined rate to minimise damage to the activated sludge. Following a period of acclimatisation it is often possible to increase feed rates to the plant and this...

    Water treatment for power plants

    The process of electricity generation from fossil fuels such as coal, oil and natural gas is water-intensive. Between 40-50% of all water abstracted and used in developed countries is used in the generation of electricity. Thus, a reliable, abundant and predictable source of raw water supply to a power plant is a critical factor in site selection. Water supplies are required to provide various process waters for the following essential main purposes such as make-up water, cooling water for steam turbine...

  • Cyanide Treatment with Hydrogen Peroxide

    Cyanides are used in a number of chemical synthesis and metallurgical processes (as simple salts or cyanide complexes). As a class, cyanides are highly toxic and must be destroyed or removed from wastewaters prior to discharge. The most common method for treating free or simple cyanide is alkaline chlorination. However, chlorination of cyanide results in highly toxic intermediates (e.g., cyanogen chloride) and, if organic material is present, chlorinated VOC’s. These compounds, together with the residual chlorine,...
