  • Removing Solids with Automatic Self-Cleaning Filters

    Introduction The “art” of filtration utilizes many methods for separating solid particles from fluids. There is often no right or wrong method. Water quality and customer requirements usually determine the “best” method for each unique situation. Ridged screens, pleated cartridges, string wound cartridges, melt blown cartridges, woven fabrics, non woven fabrics, sintered metals, granular ...

  • 100 Simple Ways To Save Water

    To improve water conservation install a rain sensor, it turns off your irrigation when it rains. Use a weather-based controller. The use of smart controllers can reduce water usage 24% a year on average. Learn about available rebate programs ...

  • Self-Cleaning Filters for Pretreatment of Membrane and UV Water Treatment Systems

    The removal of suspended solids is necessary to protect membrane systems and prevent the “shadow effect” in ultraviolet (UV) treatment systems. Recent field data has shown the effectiveness of automatic self-cleaning filters in removing suspended solids down to less than 3 microns in size without flocculants, pre-coats or granulated media. Tests have demonstrated the complete removal of particles ...

  • Shredding tyres stops zika virus breeding

    Zika is a dangerous disease threatening millions of people today in southern hemisphere. It is spread mostly by the bite of an infected Aedes species mosquito (Ae. aegypti and Ae. albopictus). These mosquitoes bite during the day and night. Once you get bitten it is too late to do much but what is important is to prevent this mosquito from breeding. Mosquitos typically lay eggs near water because ...

  • New Style Automatic Self-Cleaning Filters for Mill Cooling Water (Phase 1)

    ABSTRACT Replacement of hot-mill rolls is expensive and often requires production to cease during the process. Surface deterioration of rolls escalates as cooling water quality decreases. This manuscript will describe the installation and performance of a new cooling water filtration system in a northeast Ohio hot-roll mill that incorporates well proven suction scanning technology with ...

  • Self-Cleaning Pre-Filtration for RO Membrane Systems

    ABSTRACT A few years ago physical processes could only remove suspended solids from a water stream. Recent advances in technology now allow the removal of selected molecules and ions from a water stream by physical means using membranes. The membrane process has recently become very efficient and economically feasible for many industrial, commercial, municipal and even residential customers. ...

  • Self-Cleaning Filtration for Pretreatment of Membrane, UV and Ozone Water Treatment Systems

    Recent field data has shown the effectiveness of automatic self-cleaning filters in removing suspended solids down to less than 3 microns in size without flocculents, pre-coats or granulated media. Pre-treatment of ozone systems is often needed to remove organic solids that would utilize high amounts of ozone during oxidation leaving little for complete disinfection. Selfcleaning screen filters ...

  • Smoke Factory Chooses Automatic Self Cleaning Filter for Efficient and Effective Chiller Protection

    BACKGROUND Cooling towers dissipate both ambient and process heat in most large manufacturing facilities.  These structures facilitate the transfer of unwanted energy (heat) from a transport liquid (usually water) to the atmosphere.  Problems with efficient heat transfer, equipment protection and pathological risks to employees can most often be traced back to an issue with suspended ...

  • Gravity self-backwashing filters

    The filtration of make-up and side-stream water in closed cooling circuits, operated through cooling towers, is a fundamental step to ensure safe and continuous operations in a power plant. Water - required in large amounts for this application - should not be wasted, and the potential damages deriving from a poor treatment must be avoided at all cost. BONO ARTES has developed a technical ...

  • Using a Self Bailer on Containment Sumps to Filter Hydrocarbons

    How do you eliminate problems associated with the collection of rainwater in outdoor containment systems and maintain compliance with EPA and Clean Water Act regulations?  Since most outdoor oil storage tank sumps and oil drum spill pallets will inevitably be exposed to local precipitation and storm water runoff from nearby catchment surfaces, it is necessary to make sure you ...

  • Soil Filters

    Soil filters (in german: Retentionsbodenfilter) are facilities for the removal of nutrients and/or pollutants; typically on the level of an industrial site, a quarter or a drainage system (sub-)catchment. Usually they are located at the discharge points to surface waterbodies to ensure water quality standards. Soil filters consist of two parts: The first part is a retention pond or basin for ...

  • Combination filters

    Simply defined, a combination filter is one that does at least one other processing job at the same time as filtering a suspension. The classic example, of course, is the packed bed of activated charcoal, which acts as a remover of chemical impurities from the suspension, as well as removing dust particles - although this is actually not a very good example, because it is primarily an adsorber, ...

  • Alternative filter media for potable water treatment

    Need for Research Roughing filters at London works: Low backwash rates for filters at older works Inability to keep sand clean (rising normalised starting head loss) Vulnerability to algal laden water Loss of production at critical times during the year Objective: identify mono-medium & dual media alternatives to BSS 14/25 ...

  • Indestructible Pumps for Clean Water

    Sulzer pumps are used in the production of drinking water in many cities around the world. The special qualities that these pumps possess can be seen at the Zurich Municipal Water Utility. There, the operators have to cope with rising land and energy prices and a challenging topography. A small water flea plays a major role in Zurich. It swims around in a container of drinking water with some of ...

  • Green Filter Cleaning Machine case study

    This Technical Report Summary presents an overview of laboratory testing conducted at SwRI to evaluate the performance of a Diversi-Tech Green Filter Cleaning Machine under controlled laboratory conditions. In particular, the objective was to measure if and by how much, if any, airflow resistance, efficiency, and dust capacity changed for a given number of dust loading/filter cleaning cycles, ...

  • The role of social networks on the uptake of household water filters by women in self-help groups in rural India

    Household water treatment and safe storage (HWTS) has been shown to improve drinking water quality and prevent disease. Efforts to scale up HWTS among vulnerable populations have been limited, partly due to an incomplete understanding of the socio-cultural influences on decision-making around uptake of HWTS. In-depth interviews were conducted with women in self-help groups in rural India who were ...

  • Filter backwashing: When and how

    Backwashing filters is a necessary and important part of the filtration process. Many operating problems associated with the filtration process can be traced to delayed or inadequate backwashing. Producing a high-quality and low turbidity filtered water depends on having clean media free of cracks and mudballs. The Interim Enhanced Surface Water Treatment Rule, promulgated on Dec.16, 1998, lowers ...
