  • 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.

  • Energy reduction and coagulation process control for wastewater treatment industry

    One of the biggest costs for water-water treatment is energy consumption; the cost of which is likely to escalate with increased demand. Ineffective process control may not only be costly but environmentally impacts though the inefficient use of an un-renewable resource. Furthermore, poor process control in one area may also impinge on neighbouring processes ultimately affecting effluent water quality.

    Online Monitoring for the Demi-Water Production Industry

    Demineralization is the process of removing mineral salts as well as organic impurities from water by means of ion-exchange and can be found in various industries such as the chemical, food & beverage, irrigation and filtration industries. The consuming side of the industry relies on ever increasing quality and availability of demi-water while the manufacturers have to balance cost/output. AppliTek provides high quality analytical tools to increase process efficiency and quality control. Continuous measurements with high accuracy are carried out on the critical QC/QA parameters of the deionizing process:

  • Ozone/UV systems for Industrial, municipal, and residential wastewater treatment

    In 2004-2005 LIFETECH`s laboratory worked out an advanced oxidation process (AOP) for removal of dioxins and furans (PCDD/F), chlorophenols and other contaminants from the BCD process wastewater. Consequently, our technology was installed and from April 2006 successfully used in the `Spolana-Dioxins` Project at SPOLANA a.s. in Neratovice, Czech Republic, as a part of Special Wastewater Treatment Plant. Our supply consisted of an ozone generator with the output of 5 kg O3/h at 10% w/w ozone concentration, two reaction tanks with mixing systems, a vent ozone destructor, and a control system. The world largest project for removal of PCDD/F was managed by BCD CZ a.s., a subsidiary of Thermal and Chemical Soil Remediation Ltd.

  • EPR waste minimisation monitoring for wastewater treatment industry

    The EPR regulations have replaced the IPPC regulations and are effective from May 2009 for qualifying companies within the industrial sector and October 2009 within the water sector. They will progressively require industry to minimise waste, reduce product loss and implement improved process control. The legislation will require the operator to self monitor processes and discharges, to demonstrate effective control with particular emphasis on EPR compliance and prevention. The regulating Agency will operate a point scoring system to assess operators under the OMA-3 program and this will be used to identify how well a company is managing their processes and possibly identify areas for improvement. The Environmental Permitting Regulations require industry to install instrumentation (MCERTS approved where available) to report water quality. EPR compliance monitoring may include automatic water sampling, flow measurement, pH, turbidity and TOC water analysis. Industry will need to identify point of source emissions, take steps to correct inefficient control and alarm unacceptable process deviations. Although the legislation focuses on environmental improvement, good housing keeping also makes a lot of sense. Optimisation of process control minimises waste, reduces treatment costs and ultimately saves money.

  • 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.

    Water quality monitoring for chemical industry

    Chemical plants that produce high quantities of phenols (plastics, pesticides and pharmaceutical industries) and other aromatic organic compounds are excellent candidates for wastewater characterization via spectral analysis. Chemicals that contain conjugated double bonds absorb UV radiation remarkably well. The benefits include higher precision in process control as well as optimization of wastewater treatment.
