Transport of nitrogen in a treated-wastewater plume to coastal discharge areas, Ashumet Valley, Cape Cod, Massachusetts

The industrial production of ethanol by fermentation using molasses as main material that generates large quantity of wastewater. This wastewater contains high levels of colour and chemical oxygen demand (COD), that may causes serious environmental pollution. Most available treatment processes in Vietnam rely on biological methods, which often fail to treat waste water up to discharge standard. As always, it was reported that quality of treated wastewater could not meet Vietnameses discharge standard. So, it is necessary to improve the treatment efficiency of whole technological process and therefore, supplemental physico-chemical treatment step before biodegradation stage should be the appropriate choice. This study was carried out to assess the effect of coagulation process on decolourization and COD removal in molasses-based ethanol production wastewater using inorganic coaglutant under laboratory conditions. The experimental results showed that the reductions of COD and colour with the utilization of Al2(SO4)3 at pH 9.5 were 83% and 70%, respectively. Mixture FeSO4 – Al2(SO4)3 at pH 8.5 reduced 82% of colour and 70% of COD. With the addition of Polyacrylamide (PAM), the reduction efficiencies of colour, COD and turbidity by FeSO4 – Al2(SO4)3 were 87%, 73.1% and 94.1% correspondingly. It was indicated that PAM significantly reduced the turbidity of wastewater, however it virtually did not increase the efficiencies of colour and COD reduction. Furthermore, the coagulation processes using PAM usually produces a mount of sludge which is hard to be deposited.

The Church

In 1822, from his Conway home in the shadow of New Hampshire's White Mountains, one Dr. Porter surveyed the nation's religious landscape and prophesied, “in half a century there will be no Pagans, Jews, Mohammedans, Unitarians or Methodists.” The prophecy proved false on all counts, but it was most glaringly false in the case of the Methodists. In less than a decade, Porter's home state became the eighth to elect a Methodist governor. Should Porter have fled south into Massachusetts to escape the rising Methodist tide, he would only have been buying time. True, the citizens of Provincetown, Massachusetts, had, in 1795, razed a Methodist meetinghouse and tarred and feathered a Methodist in effigy. By 1851, however, the Methodists boasted a swelling Cape Cod membership, a majority of the church members on Martha's Vineyard, and a governor in the Massachusetts statehouse.
