Chat OnlineGL V Australia has developed a variable dilution feed system for thickeners that provides greater flexibility in dilution control on thickener feed systems.. The new system is based on the technology introduced with the company s patented Eimco E-Duc feed dilution system. Released in 1999 the E-Duc system uses the head of the undiluted feed as the driving force for the eductor nozzle which
Chat OnlineThe table below lists the recommended flow ranges and dimensions of standard floc tubes. Alternate configurations can be designed if needed. Models FT-43 and smaller use Schedule 80 PVC pipe while larger models use Schedule 40 PVC pipe. Floc tubes for higher temperature flows can be constructed with CPVC piping.
Chat OnlineFlocculant is added into the feed pipe and mixes with the solids forming larger agglomerations that will rapidly settle to the bottom of the Thickener. The feed well is oversized allowing entrapped air contained within the feed slurry to rise and dissipate so it does not enter the main settling zone within the Thickener.
Chat OnlineThickeners — or Clarifiers depending on the application — can be used to recover immediately reusable process water as well as extract fines and other materials. Thickeners can be used by mineral and aggregate producers as well as by environmental contractors in industries such as wastewater management. The benefits of Thickeners can vary from user to user depending on the producer s
Chat OnlineThickener control has a number of complexities such as varying feed characteristics. Changes in feed concentration solids specific gravity particle size distribution pH temperature and reaction to flocculant can all contribute to variations in performance. Accurate information about what s happening inside the thickener is difficult to get.

Chat OnlineThe feed rate solids flux shown is calculated in the next step. Figure 6. Batch flux curve extrapolated to 300 kg/m 3 Design Procedure The thickener area is also required for this calculation. Guess the thickener area for the first iteration. Several iterations of area may be required to achieve a practical thickener size and pumping rate.
Chat OnlineThe major international thickener suppliers each have their own method to use clarified water in the thickener to dilute feed. After selection of the optimum flocculant type dosage and feed dilutions the use of automatic control of flocculant feed is the next important step.
Chat OnlineDry solids feed rate To be used as a feed forward signal for the flocculant dosing control loop a pair of nucleonic density and inline flow meter can be installed. This predicts the flocculant dosing based on what dry solids feed is expected to enter and not just reacting to
Chat OnlineIt is common industrial practice to add polymeric flocculants directly into slurry streams during flow through pipes. However very little information is available on the specific requirements for such polymer addition systems and their design and operation appear to be largely intuitive.

Chat OnlineFlocculants are categorized as anionic nonionic or cationic and therefore affected by pulp pH. Basic thickener operation will have you understand the simple electrics of water. For lack of proper testing you will need to buy a floc that fits your chemistry or modify it using lime.
Chat OnlineThe Flocculant-treated feed slurry enters through the central feed well or central diffuser drum which disperses the feed gently into the thickener. The feed suspension falls until it reaches a height where its density matches the density of the surrounding suspension and it spreads at that level.
