Transite Pressure Pipe for Force Mains

Transite pressure pipe for force mains assures the same economies of lowered installation and maintenance costs as does Transite sewer pipe. Its

high flow capacity (C =

140) and free dom from tuberculation help keep pumping costs low. Easily-assembled Simplex couplings provide tight, flexi ble joints, each capable of 5 degrees deflection.

Transite pressure pipe is available in

sizes 3 in. to 36 in. in Classes 50, 100, 150 and 200, for recommended working

pressures of 50, 100, 150 and 200 p.s.i.,

respectively. For further information on Transite

pressure pipe for force mains write* for

Brochure TR-11A. All of the above

mentioned publications may be ob

Enduring Grating for Sewage Plant Installations

The increasing importance being given to modern, labor-saving facilities in public works plants focuses the at tention of engineers on the easy instal

lation, with minimum labor, of open steel grating for a wide range of uses.

Klemp Welded Steel Grating pro vides strong, safe and lasting grating of low original cost and maintenance free service over long years of the se

verest duties. It is of one-piece con struction in all widths and lengths for

every requirement.

Klemp grating (Figure 1) is accu

rately prefabricated to fit any area, or

around pipes, columns, or other ob structions. The hot-rolled steel hex

agonal bars, placed at right angles on top of flat bearing bars set on edge and then electro-welded, provide a non

KOMLINE-SANDERSON ENGINEERING CORPORATION

Ridgewood, N. J.

During the past several months, this concern has undertaken a development program covering the application of a

Titeflex-Wright Cord Filter to the

sludge drier at Plainfield, N. J. In the course of the work an investigation was

made regarding the simplification of auxiliaries at present thought neces

sary in the operation of vacuum filters. The work has been highly successful.

The operation of the cord filter indi cates a number of inherent advantages ; there is no blinding of the cloth, rates are high, and the unit easily adapts it self to sludges of various densities and

grease contents.

The spray drying of filter cake is ac

complished effectively by the same

style apparatus that has proven so de

pendable in nine years of trouble-free

operation on thickened sludge. In the

operation of the drier, advantage is

taken of the fact that filter cake is

easily extrudable. A hopper-fed Roots

type pump revolving at 5 r.p.m. ex

trudes the cake through two 6-in. pipes onto the spray bowl, where it is broken

up into fine particles for rapid drying in suspension.

With respect to the simplification of vacuum filter auxiliaries, the Komline Sanderson Engineering Corp. has been able to work out a single unit for evacu

ation of filtrate and entrained air, plus wash water from the cords, eliminating the complement of compressor, vacuum

and filtrate pumps, tanks and piping usually required.

The design of the drier, filter and furnace have been incorporated into a

single, integral building, with capaci ties from 20 to 250 tons filter cake per day.

LAM0TTE CHEMICAL PRODUCTS COMPANY Towson 4, Md.

As in the past, the LaMotte Chemical Products Company is maintaining a

complete program of new develop ments, and improvement of the Stand ard LaMotte Equipment that has served the sewage works operator so

well over the past 25 years. The con tinuation of this policy has resulted in

improved chlorine equipment, embody ing the latest developments and recom

mendations for the accurate determina tion of free chlorine and chloramines, and the many ramifications of the chlo

ri?e problem, including the new Ortho Tolidine-Arsenite Test.* Improvements and accessories for the chlorine and

pH tests include a new Plastic Block

Comparator which, while possessing many refinements made possible by the application of improved engineer ing methods,' still follows the basic de

sign of the well-known LaMotte Block

Comparator, and may be used inter

changeably with existing LaMotte

equipment. For the many laboratories that pre
