其優點為：分戶支管短，較節約管材，管道水頭損失也較小，缺點是：水表分散設置，抄表人員勞動強度較大；通常室內消火栓箱也明設于休息平臺處，因而使本來就擁擠的休息平臺更為局促，給住戶通行帶來不便。c.水表每層集中設于水表間內，分戶水表整齊靠于墻面。其優點同方式b相同，缺點是：分戶管道必須沿公共走道樓板下引入室內，因而走道內要求設吊頂。d.將傳統的普通機械式水表改換為遠傳水表或IC卡智能型水表。遠傳水表計算準確且無需抄表，此卡表需用戶預存入一定數額水費，將充值后的IC卡插入水表的讀碼器中即可用水。

可見，鄰酸鈉是從黃鐵礦的混合精礦平分選出有色金屬硫化物的一種選擇性很強的捕收劑。在捕收劑存在的條件下，增加電解質(NaCl、Na2SO4)等，將會影響精礦的產率。在無捕收劑的條件下，在電解質溶液中，有色金屬硫化物的浮選一直不能令人滿意，在別離浮選精礦中，銅和銀的收回率分別為6.9%和6.2%。只運用一種基酸捕收劑來浮選這些金屬的細粒硫化礦藏，相同是很不行的，收回率僅到達12%～12.5%。在這種情況下，須研討選擇性捕收劑和低濃度電解質溶液(.1克當量/升以下)的組合對浮選目標的影響，由于預先實驗已查明，在礦漿液相中高濃度鹽阻止基酸捕收劑在選別礦藏表面上的附著。
