Flow & Load Surveys Flow and Load surveys help manage compliance, DAF plans and process efficienciesFlow and load surveyAs part of our industrial wastewater services packages, we can implement flow and load surveys. A flow and load survey can save a company vast sums of money on their water bills and are an essential requirement for wastewater treatment works and industrial facilities.Flow and load surveys are short term surveys used to understand the water flow and strength of trade effluent. These surveys may be conducted to understand weaknesses in the process or in a DAF plan, and as a way to measure compliance with the consent licence.The quality of trade effluent is determined by kg/day and is often based on:Chemical Oxygen Demand (COD) Biological Oxygen Demand (BOD) Settled Solids Suspended SolidsFlow is the volume of the industrial effluent and load is the chemical content.Flow survey Our approach uses an ultrasonic wastewater flow monitor to determine flow rates. An account manager from the industrial trade effluent services team would work with your team to understand how your site works and the processes that affect the flow. They would then determine the length of survey required and the time increments measurements are to be recorded for the most accurate results. Load survey We would use an automatic wastewater sampler to take 24 samples over a course of time determined by the regular process of the facility for the most accurate reading. The wastewater sampler could be connected to the flow meter to conduct proportional flow samples. The samples would then be sent to a specialist laboratory for analysis and to determine the level and load.Related Products Full DetailsAdd to Quote ORAKEL Area Velocity Flow Meter A robust, doppler velocity sensor that uses ultrasonic technology to measure wastewater flow with improved accuracy and reliability. ORAKEL Area velocity flow meter Full DetailsAdd to Quote ORAKEL The ORAKEL System is ideal for all your water monitoring equipment needs, measuring both water flow and water quality at the same time. Created as a modular system, a wide range of water quality sensors can be added to measure various characteristics, such as pH, COD and suspended solids, for a truly bespoke and cost-effective solution. Full DetailsAdd to Quote Dissolved Oxygen Optical luminescent devices which are extremely resistant to abrasion, extremely stable, and have greatly reduced maintenance and whole life costs. The ORAKEL Dissolved Oxygen sensor has no chemicals or moving parts. It is stable and reliable making it excellent for process controls and is suitable for all Dissolved Ovygen applications. Full DetailsAdd to Quote Turbidity The ORAKEL Turbidity monitor automatically varies the light output so that the turbidity can be measured independently of background light and electronic drift. It is ISO 7027 compliant and covers a range of 0.01-1000 NTU (0.01-2000mg/l depending on the sample). The ORAKEL System determines true turbidity and/or suspended solids in water, using a nephelometric measurement of scattered light in accordance with ISO 7027. The sensor uses lifetime-based optical technology to provide an extremely stable, accurate, low maintenance sensor with no moving parts and no consumables. Full DetailsAdd to Quote TOC, COD, UV Absorption The ORAKEL COD/TOC Sensor uses UV254 light as a surrogate measurement for detecting organics in water. It is designed in modular form so that it can be integrated with other sensors, such as pH, turbidity and dissolved oxygen, to provide all the tools needed for either a stand-alone UV254 analyser or as part of an effluent discharge monitoring system. The ORAKEL COD/TOC Sensor provides online continuous organics monitoring utilising a 254nm ultraviolet light source. Full DetailsAdd to Quote pH Probe The pH5 electrode has a double-junction reference to prevent contamination of the reference from sample components. This design gives the electrode a longer life compared to ordinary electrodes (up to 3 yrs). The electrode also has a hemi-shaped glass measuring surface which is more durable than the traditional bulb-shaped glass. Sitting at the top end of the market place, the ORAKEL pH probe has a longer life and lower maintenance requirements. Typically it only needs calibrating once every two or three months, making it a very cost effective solution.
