  • One process removes arsenic & iron from water in small Utah town

    The Safe Drinking Water Act brought with it tough arsenic compliance standards, forcing cities large and small to comply with a maximum contaminant level of 10 parts per billion (ppb) or face stiff fines and even the potential shutdown of wells. Smaller towns such as Cannonville, Utah, face the most difficult challenge, due to manpower and budget constraints. Cannonville turned to Filtronics, ...

  • Co-optimisation of phosphorus and nitrogen removal in stormwater biofilters: the role of filter media, vegetation and saturated zone

    Biofilters have been shown to effectively treat stormwater and achieve nutrient load reduction targets. However, effluent concentrations of nitrogen and phosphorus typically exceed environmental targets for receiving water protection. This study investigates the role of filter media, vegetation and a saturated zone (SZ) in achieving co-optimised nitrogen and phosphorus removal in biofilters. ...

  • One step, low pH iron and organics removal - Case Study

    Review For over seven years, the semiconductor facility performed routine on-site cleans of their reverse osmosis (RO) membranes using RoClean P111 with good results. However, over a six month period in 2015, membrane cleaning frequency increased to once a month and permeate flows could not be sufficiently restored. An Avista application specialist visited the site to personally monitor the ...

  • Treatment of heavy metals by iron oxide coated and natural gravel media in Sustainable urban Drainage Systems

    Sustainable urban Drainage Systems (SuDS) filter drains are simple, low-cost systems utilized as a first defence to treat road runoff by employing biogeochemical processes to reduce pollutants. However, the mechanisms involved in pollution attenuation are poorly understood. This work aims to develop a better understanding of these mechanisms to facilitate improved SuDS design. Since heavy metals ...

  • How to Treat Water and Remove Arsenic

    Arsenic is a naturally occurring element from the earth’s crust. Around the world, many countries have groundwater that is steeped in arsenic. Until recently, governments haven’t realized just how bad arsenic was for people, even in minute concentrations. In 2001, the US Environmental Protection Agency felt it necessary to lower the drinking water arsenic standard from 50 parts ...

  • Technology for treatment of groundwater simultaneously containing iron, manganese, ammonium and organic matter

    The groundwater used as drinking water often contains unacceptable amounts of iron and manganese compounds and ammonium ions. These substances are efficiently removed using conventional technologies (aeration and filtration through granular media filters). However, the efficiency is drastically reduced for water containing considerable amounts of organic matter, which usually enters the water ...

  • Low cost processes for the removal of phosphates in water and wastewater

    This paper presents a synopsis of various low-cost techniques employed for the removal of phosphates from water and treated wastewater. Techniques employed include seawater flocculation and coagulation/flocculation using bittern, adsorption on fluidised raw dolomite bed, and filtration through iron and aluminium coated filter media. Seawater flocculation at a seawater concentration of 10% ...

  • Project profile - Lummi Island, Washington arsenic, iron, sulfide treatment system

    Background In mid 2004, AdEdge Technologies Inc. (AdEdge) was selected by Miller Water Association and Anvil Corporation to assist in the design of a fullscale arsenic treatment project for this small community. Arsenic levels are alarmingly high at 0.18 mg/l, 18 times higher than the new Federal standard of 0.010 mg/l. In addition to arsenic, many of the homeowners using the water ...

  • Project profile - Village of Corona, NM iron and manganese reduction

    Background In the fall of 2008, AdEdge was selected by Village of Corona, NM to design, manufacture, and startup a water treatment system for the removal of iron and manganese. The water system that serves approximately 100 connections at Corona was plagued by high iron and manganese in the main water supply with iron from 0.26 – 2.8 mg/L and manganese levels from 0.094 - 0.17 ...

  • Chemical Phosphorus Removal from Onsite Generated Wastewater

    ABSTRACT Phosphorus originating from onsite generated wastewater is becoming recognized as a major cause of impairment to streams and lakes. Efficient, low maintenance technologies are needed to reduce discharge levels. Removing phosphorus using luxury uptake or precipitation followed by settling, as is common at municipal wastewater treatment plants, is not practical for onsite generated ...
