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 wastewater disposal regulations, company mandated green initiatives, public perception of industrial impact on the environment, or concern over the quality and quantity of the water supply.

  • 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.

  • 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 reliable and timely means of ensuring that treatment processes are operating efficiently and that EPR compliance is maintained.

    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 before discharge of effluent wastes. This can be done manually with handheld instruments or automatically with in-line monitor/controllers.

  • 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 can again be managed using the Strathtox Respirometer. An alternative approach is to undertake toxicity reduction procedures, such as neutralisation or acid hydrolysis, in pilot-scale laboratory studies. The Respiration or the Nitrification Inhibition Test may be used for this. In the future, toxicity reduction may be stipulated by local authority, water company or publicly-owned treatment works prior to giving discharge consents. Toxicity reduction may be evaluated using toxicity tests on activated sludge provided by the treatment works.

  • 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, create additional environmental problems. Consequently, there is a growing need for alternative, non-chlorine methods for destroying cyanides. Peroxygen compounds such as hydrogen peroxide, peroxymonosulfuric acid (1), and persulfates (1) are effective alternatives to alkaline chlorination for destroying free and complexed cyanides. The choice of peroxygen system depends on the reaction time available, the desired products (cyanate, or CO2 and NH3), the types of cyanides being treated (free, weak acid dissociable, or inert), and the system economics. Treatment with Hydrogen Peroxide While hydrogen peroxide will oxidize free cyanide, it is common to catalyze the reaction with a transition metal such as soluble copper, vanadium, tungsten or silver in concentrations of 5 to 50 mg/L (2).

  • Sulfide Oxidation with Hydrogen Peroxide (H2O2)

    Sulfide Odor Control Sulfide is found throughout the environment as a result of both natural and industrial processes. Most sulfide found in nature was produced biologically (under anaerobic conditions) and occurs as free hydrogen sulfide (H2S) - characterized by its rotten egg odor. We are most likely to encounter biogenic H2S in sour groundwaters, swamps and marshes, natural gas deposits, and sewage collection/treatment systems. Manmade sources of H2S typically occur as a result of natural materials containing sulfur (e.g., coal, gas and oil) being refined into industrial products. For a variety of reasons - aesthetics (odor control), health (toxicity), ecological (oxygen depletion in receiving waters), and economic (corrosion of equipment and infrastructure) - sulfide laden wastewaters must be handled carefully and remediated before they can be released to the environment. Typical discharge limits for sulfide are < 1 mg/L. Sulfide Treatment Alternatives There are dozens of alternatives for treating sulfide laden waters, ranging from simple air stripping (for the low levels present in groundwaters) to elaborate sulfur recovery plants (used to treat several tons per day at refineries and coal burning power plants). There are processes based on biology (using compost filters, scrubbing media, or inhibition/disinfection), chemistry (oxidation, precipitation, absorption, and combination), and physics (adsorption, volatilization, and incineration). Each process occupies a niche which is often defined by the scale and continuity of treatment, whether the sulfide is in solution or is a gas, the concentration of sulfide involved, and the disposition of the sulfide containing medium. However, for reasons relating to convenience and flexibility, chemical oxidation (using hydrogen peroxide) continues to grow in its scope of application. Treatment with Hydrogen Peroxide While other peroxygens such as permonosulfuric (Caro’s) acid, peracetic acid, and persulfates will oxidize sulfide, their use for this application is overkill. Hydrogen peroxide (H2O2) is considerably simpler and more cost-effective. H2O2 may control sulfides in two ways, depending on the application: Prevention - by providing dissolved oxygen which inhibits the septic conditions which lead to biological sulfide formation; and Destruction - by oxidizing sulfide to elemental sulfur or sulfate ion.

  • BOD and COD Removal

    Hydrogen peroxide (H2O2) has been used to reduce the BOD and COD of industrial wastewaters for many years. While the cost of removing BOD / COD through chemical oxidation with hydrogen peroxide is typically greater than that through physical or biological means, there are nonetheless specific situations which justify the use of hydrogen peroxide. These include: Predigestion of wastewaters which contain moderate to high levels of compounds that are toxic, inhibitory, or recalcitrant to biological treatment (e.g., pesticides, plasticizers, resins, coolants, and dyestuffs); Pretreatment of high strength / low flow wastewaters – where biotreatment may not be practical – prior to discharge to a Publicly Owned Treatment Works (POTW);Enhanced separation of entrained organics by flotation and settling processes; and Supply of supplemental Dissolved Oxygen (DO) when biological treatment systems experience temporary overloads or equipment failure. http://www.h2o2.com/industrial/applications.aspx?pid=104&name=BOD-COD-Removal
