concentration of TSS to cell I was 150 [+ or -] 43.7 mg [l.sup.-1] and in cell II was 32.6 [+ or -] 15.5 mg [l.sup.-1].These concentration were reduced to a minimum of 40mg [l.sup.-1] and a maximum of 70 mg [l.sup.-1] by cell I and 3.5mg [l.sup.-1] and 27.4 mg [l.sup.-1] by cell II(Tabs.
samples were obtained from the feed tank's recirculation line (used to keep the tank mixed, as previously described).
The retrofit was accomplished by taking an influent/effluent distribution box out of service, installing new influent
and effluent piping at the clarifier, and other minor piping modifications.
As shown in Figure 2, the influent
concentrations of nitrate and sulfate ranged from 10-50 mgN/l and 100-300 mg S[O.sub.4.sup.2-]/l through the experiments, respectively.
However COD removal rate (E) increased non-linearly when the COD influent
concentration (So) was increased.
Differences in concentrations of the estrogenic chemicals measured in the two study effluents reflect either differences in the influent
, differences in effluent dilution, and/or the different treatment processes employed in the works, as established in other studies (Kirk et al.
The engineers' objectives were to rehabilitate or replace the influent
line, stop the infiltration, fill voids, and provide structural reinforcement in the pipeline; rehabilitate, protect the concrete, and seal leaks in the diversion chamber; and rehabilitate or replace the cast iron sluice gates, arrest their corrosion, and improve their serviceability and operability.
Environmental Pipeliners, along with grouting subcontractor T Luckey Sons', commenced preparation for the trenchless repair of the influent
sewer in July 2001.
The effects of influent
flow rate, initial As(V) concentration, influent
pH, adsorbent mass, adsorbent grain size and operating temperature on adsorption removal capacity were investigated.
Rawalpindi -- As many as three persons were injured when influent
people equipped with arms allegedly attacked a house situated at Safari Enclave-II of a Private Housing Society of Police station Saddar Baironi area.
where Q is the total volumetric flow rate, which represents the flow rate of the influent
fracture in this study, [nabla]P is the pressure gradient, w is the width of the fracture, e is the uniform aperture of the idealized smooth fracture, [mu] is the dynamic viscosity, k is the intrinsic permeability defined as [e.sup.2]/12[5, 27], and A is the cross-sectional area equal to ew.
fully contacted with semisoft media in the upward flow, then overflow into the membrane area.
