JULY 20TH, 1944 FLIGHT Advertisements, v ROLL ON THE BARREL! r For miles and miles over the dry plains of Central Chile the peon had to make his way with his crude appliance for carrying water to the toiling workers in the Antofagasta nitrate fields. But now, all over the tropics, E.C.D. mobile equipment can ease the problem of water supply just where it is hardest. The unique patented cell which makes and injects fresh, electrolytic sodium hypochlorite of predetermined strength enables the apparatus to treat water from any natural source—whether it be a suspect well, a dank pond or even water heavily contaminated by sewage. So fine a bactericide is electrolytic sodium hypochlorite that Lord Horder's committee on shelter hygiene recommended its use for spraying shelters " because of its intrinsic merit." That is the secret and success of E.C.D. equipment in providing absolutely pure, clear water without taste, smell or trace of chlorination. Varying sizes give from 500 to 3,000 gallons an hour. • • j **ft Advice on matters relating to water treatment can be obtained from WATER TREATMENT LCD.
