PRETREATMENT EVALUATOR FOR PORTABLE TYPE SEAWATER DESALINATION PLANT

PROBLEM TO BE SOLVED: To provide a pretreatment evaluator for a portable type seawater desalination plant capable of being carried into an on-site sea area where the introduction of a seawater desalination plant is examined, and easily acquiring on site the permeability of seawater by various kinds of pretreatment equipment.SOLUTION: A pretreatment evaluator for a portable type seawater desalination plant 1 can accommodate a plurality of small-sized modules which simulate sand filter devices and membrane separation devices to make a portable type housing accommodate: a plurality of inflow ports (5a, 5b), outflow ports (6a, 6b), and drain ports (7a, 7b, 7c), arranged to correspond to flow inlets that introduce treatment object water provided at different positions for each of the small-sized modules, flow outlets out of which treatment water after treatment flows, and drain ports that discharge drain; and channel switching parts (8a-8d) that switch the connection relation ship between a plurality of inflow ports, outflow ports, and drain ports.SELECTED DRAWING: Figure 1 【課題】海水淡水化プラント導入を検討する現場海域に持ち込み可能で、各種前処理装置による海水の透過性を現場で容易に取得し得る可搬型海水淡水化プラント用前処理評価装置の提供。【解決手段】可搬型海水淡水化プラント用前処理評価装置１は砂ろ過装置及び膜分離装置を模擬する複数の小型前処理モジュールを収容可能とし、小型前処理モジュール毎に異なる位置に設けられた被処理水を導入する流入口、処理後の処理水が流出する流出口、ドレンを排出するドレン口に対応するよう配された、複数の流入ポート（５ａ，５ｂ）、流出ポート（６ａ，６ｂ）、及びドレンポート（７ａ，７ｂ，７ｃ）と、複数の流入ポート，流出ポート及びドレンポートの接続関係を切り替える流路切替部（８ａ〜８ｄ）とを可搬型の筐体内に収容する。【選択図】図１
